My limited thoughts are these

...... You say it was since the last rip to the drags, hmm. The things that are stressed the most would be clutch, transmission, U-joints, axle shafts and their U-joints. I would probably add in the motor mount as well, but from your description, I'm not 100% sold on that.

I would think that maybe the pilot bushing or the input shaft bearings could be the culprit. I say that because its happening on hard acceleration.

It almost sounds like there may be a combination of problems. The hum can be wheel bearing related as mentioned, or still a bad U-joint. U-joints are hard to pin down sometimes because alot of times, they dont make it obvious that theyre bad, unless theyre totally shelled.

Well, thats my .02
